In this video, I'm gonna show you how to take your audio in your RetroPie setup from this to this
With this
Stick around cause this is TechWizTime
Hey guys, hope you have an awesome week
My name is Jonathan And this is TechWizTime where I bring new technology tutorials and review videos
And this video is all about this little guy here. This is the HiFiBerry Amp-2
It's actually an amplifier for a Raspberry Pi, which connects through the little pins on top
Or the GPIO pins and it's powered from anywhere from 12 volts to 24 volts external power supply
Like this one here
Before we go any further I want to just fully disclose that HiFiBerry did actually send this out to me to review in this video
But no money has exchanged hands and all opinions are my own
Now being as this is the Amp-2 there have been a few previous releases to this one
Except the difference with this one is that it's a black board and
It's also more powerful and cheaper
So let's look at the specs
So like I mentioned before it can be powered by a 12 volt-24 volt power supply and can output 60 watts of power
How awesome is that?
The other thing about this is that it can output at 192 kilohertz 24-bit so that puts it in the HD audio category
Now what I'm doing in this video is I'm showing you it inside of an arcade stick with the Raspberry Pi inside as well as 2 3 watt speakers
Now this is the amazing thing the audio that you heard at the very start, which I'll play again now
Is from those tiny 3 watt speakers
Now these are really tiny they're only 2 inches
They're three watt 8 Ohm
And that brings me another point as well this actually will power 4 to 8 Ohm speakers
So that's amazing right there
So the beauty of the HiFiBerry Amp2 is that you can set it up with the Raspberry Pi operating systems like Runeaudio or Volumio
Oh, and that will allow you to control the level of audio however with my particular setup
I've got actually set up some extra things in RetroPie to make it work properly
I'll have a link down in the description where you can follow along with my tutorial on how to do that properly
So setup was relatively easy you just have to connect the Raspberry Pi to the HiFiBerry
Make sure the positive and negative wires are in the right holes
Hook in the barrel power and away you go
So to set this up in RetroPie you need to get to the bash prompt and you need to type in "sudo nano /boot/config.txt"
Here we're going to edit some things so the Raspberry Pi and RetroPie recognizes that there's the board that will output the audio
So what we need to do is we need to look for the line that says "dtpatam=audio-on"
Once we've found this line we need to get rid of it completely so remove that now
Next from where we remove that line we need to add in this following line "dtoverlay=hifiberry-dacplus"
Save the file by pressing Ctrl X, Y and Enter
And reboot your RetroPie installation and we're away
Now when we boot back into RetroPie and start up a game
We can hear the audio now coming through properly through the speakers.
How awesome is that?
So like I said this thing is loud now these are only a tiny three watt speakers
But they can really pump out the audio with this amplifier
I've got a few upcoming projects that I'm going to be working with the HiFiBerry Amp2 and the Raspberry Pi, so
If you want to get notified of those then make sure you subscribe to this channel and also click on the bell icon to get notified too
So my regular subscribers will know that I've changed the setup just a little bit
The background is the same here in this video but this desk is new
And it's going to be a new addition to this channel because it just it really helps me
Instead of having that little lap table that I used to use in the middle there
So let me know what you think down in the comments.
Also I've just hit a few milestones on social media I've hit 2,000 followers on Instagram
I've hit 1500 followers on Twitter
And also almost a thousand followers on my Facebook page
And my facebook group has just started, so there's only about a 100-150 people in there at the moment, but
It is growing at a really steady rate, so if you want to come over and join us
All the links to those will be down in the description below
